BB社「現TI社」高精度・高速Difet(R)オペアンプ「OPA637AP」(1回路)2個セット。1回路⇒2回路変換DIP「HG版」両足金付 新品

The
Burr-Brown「現TI社(テキサスインスツルメント)」OPA637APです。高精度・高速Difet(R)オペアンプシングル(1回路)オペアンプ。一応本物です。データは「TI社」からの物です。。
最近良く見る「OPA627AU」(2回路DIP化版)ではないです。正真正銘のOPA627系チップの「OPA627AP」の上位版になります。。

オペアンプの交換は基本的に自己責任で御願い致します。相性等のクレームはご遠慮下さい。相性等はご自身でお調べ下さい。また、ネットで検索して頂ければ出ますが「発振」し易いです(結構温度上がります)。自分はミニアンプに入れていますが、天板に放熱板追加で使っています。付属のコンデンサー付きの2回路化DIPは「発振防止仕様では無いです」自分はこの使っていますが、温度が上がる可能性が気になる方は入札はご遠慮下さい。もしくは一度調べてから御願い致します

付属品はシングルオペアンプ「1回路」をDUAL-DIP「2回路仕様」に変換する下駄基板「8ピンDIPチップ」にする基盤です
こちらはコンデンサ実装済ハイグレード版になります。基板上には0.1μF50Vの薄膜高分子積層コンデンサを実装しています積層コンデンサが不要な方、電源部等でコンデンサの相性で不要な方はコンデンサ無しの通常バージョンも別件にて出品しています

オペアンプ2個と変換DIP1個の出品です

非Unity-GainでOPA627よりさらに高速なシングル(1回路)オペアンプ。ハイエンドオーディオアンプや、ヘッドフォンアンプ用のオペアンプとして人気。

梱包ですが、梱包代金等は頂いていませんので基本的に簡易梱包で発送致します。。無理な梱包を強要される方は入札を御遠慮下さい。。
あと自分はタバコを吸いませんのでタバコのヤニによる匂いや汚れはありません。
申し訳有りませんが落札後はノークレーム。ノーリターンでお願い致します。以上を御理解した上で興味がある方がいましたら御入札お願い致します。

International Shipping Methods
Proxy bidding and purchasing services are becoming increasingly convenient. However, overseas shopping carries certain risks and issues. To reduce these risks and enhance shopping safety, please be sure to read the following information:

1. International Shipping

   Air Freight: If the item status is not confirmed within two days after the arrival notice, any customer complaints cannot be addressed with the seller.

2. After Receiving the Product

Please confirm and inspect the product as soon as possible to ensure that the product specifications, quantity, accessories, and description are correct

If, unfortunately, there are any issues, you can refer to the following examples on how to report related product problems:
1. Example of missing product information
2. Example of product not matching provided information
3. Example of damaged product information

Important Notes: 1. If the seller is unwilling to ship overseas or is unaware that the product will be shipped overseas, the international shipping cost for returns or exchanges will need to be borne by the member. You may refer to the EMS e-Express fee inquiry from the post office. If it involves alcoholic beverages or items that affect flight safety, the post office cannot be used for shipment, and only DHL can be used to ship back to Japan.
2. During the product complaint handling period, please retain the complete outer packaging of the product (including the shipping label information), and refrain from attempting any repairs or altering the original condition. Any modifications may result in the inability to process the case.

3. After Inspecting the Product

After receiving and inspecting the item, if you have any questions, it is recommended to contact Letao within 2 hours. Here are some reminders:

1. Please do not unpack, use or repair the received item yourself, and be sure to keep the original packaging to facilitate subsequent handling of related matters, so as to avoid changes to the item that may cause the seller to be unwilling to process.

2. You can call customer service, and the customer service will leave a message for you as below. Please provide the following information:
"Hello, we will first help you establish a complaint case for Product ID: _______ .But we need you to 2-3 clear photos of the product issue, including photos of the product problem, product packaging, shipping details slip, and outer box. Send them to service@letao.my and inform us of your desired resolution (failing to provide this may result in an inability to process subsequent matters). After sending the email, notify us in the customer service message. We will confirm with the seller as soon as possible. and if there are any related questions, we will contact you through the customer service message. Thank you for your cooperation."

Please provide:
1. "Product ID"
2. Photo of the "Delivery Note" (if any)
3. Photos of the outer box (including inner and outer packaging)
4. Photos of the product (Please include relevant descriptions to help us confirm with the seller)

Important Notes:
1. Do not include foreign text or other products in the background of the image.
2. Please keep the complete product packaging (including the shipping label information), and refrain from repairing or altering the original condition on your own, as any changes may result in the case being unable to be processed.
3. Please provide the relevant information within 48 hours to avoid missing the golden hour for reflection and causing situations that cannot be handled.
4. Due to 99% of Japanese sellers being unwilling or unaware of shipping goods overseas, if a seller is willing to handle the issue, the goods must be sent back to Japan, and the international shipping costs incurred must be borne by the member. Letao will use postal EMS international express to send the goods back to Japan.
5. As the goods are purchased from overseas, it may take approximately one to two weeks to complete the relevant processing procedures when issues arise with the goods. Please be reminded that you can inquire about the approximate cost through the EMS service at the post office.

4. FAQ

1. Issue of Authenticity: If antique or branded goods are found to be counterfeit upon receipt, clear photos showing the differences between the genuine product and the imitation must be provided as evidence. If unable to provide relevant proof, assistance can be sought to find a third-party reputable organization for a premium authentication service .
2. Leaking Iron Teapot: If an antique iron teapot is leaking, please take clear photos of the leaking area and provide them.
3. Transport Damage: If the goods are damaged during international shipping (to the pickup point), you need to provide photos of the outer packaging of the parcel and clear photos of the damaged goods' outer packaging.

※ Note: Photos provided to sellers should not contain any foreign-related information.
