CHIP CAP貼片電容來說, 以下品牌有何優劣之處?

Question

設計及採購選用那款較好?

1. MURATA
2. AVX/KYOCERA
3. TAIYO YUDEN
4. TDK
5. SAMSUNG
6. 風華

滿意, 但風華是國產貨, 不是台灣的.
希望有更多答案.

Answer 1

Firstly, we have to classify them into different catagories:

1/ Japanese brand (premium grade)
- Murata
- AVX/Kyocera
- Taiyo
- TDK

2/ Korea/Taiwan(lower grade)
- samsung
- 風華

Murata: should be the best in the manufacturer of all MLCCs, in terms of quality and customer support.Strong in common item/ RF application such as 0402, and small value.

TDK: should be ranked the 2nd, quality is the same as Murata, but now the Leadtime is hard to fulfil due to low production rate (actually it happens for all chip cap now too). Strong in hi-cap, like value higher than 105, mainly using in car industry or the if they gonna use that in extreme conditions.

AVX and Taiyo:price comparatively higher than TDK and Murata, not much people using them.

Samsung/ 風華 : considered lower grade, the price is like 30% or more cheaper then the premium brands, lower quality, not recommended for high precision products.

For design/sourcing, it really depends on your application, please contact your local distributor once you decide which brand to use.

Hope that helps
