I think you got a general idea on Kingtronics radial mlcc capacitor from our promotion in 2011, right?

I want to know that if my cross guide is helpful for you? Does it work? Did you meet inquiry from these brands? Let me help you cost down!
Or, did you meet any difficulty when promote to customer? Let me help you solve it

MKT -Radial Multilayer Ceramic Capacitors (Mono Cap)  Cross Guide 

Kingtronics Series AVX Murata  Kemet Vishay
MKT series SR, SA series RPE series C315-C350 K (Mono Cap)
Kingtronics Series NIC Nippon  TDK Panasonic
MKT series NCM   NCMA THD series  FK Series  ECU-S



As weknow that you are distributor of components, maybe it is better to submit FREE samples when you visit customer.
I think you can win more orders after promotion.


1. Kingtronics price is unbeatable in the market, short lead time 3-4 weeks.
2. Its weight is light. when you import components, you can buy some radial mlcc capacitor together, won't increase much your freight cost. (normally bulk package: 1000pcs/bag, 1 bag around 100g)
3. We prepare many hard copies, file folders, free samples,,,,we give full support.

Could you please share with me about your market on this product? We can make a promotion plan for your sales together !

I will be glad to quote for you always.

Waiting for your reply.
