ECS-SR1-B
SMD CERAMIC RESONATOR
The ECS-SR1-B Series SMD ceramic resonator includes built in
capacitors for reduced component count. The SMD Ceramic
resonator is an excellent low cost frequency control solution
when absolute frequency accuracy is not important.

Application Information Request
Attention:
All Customers
From:
Mike Huennekens, Director of Marketing and OEM Sales
Subject:
Ceramic Resonator Application Information Request
ECS is requesting that you complete the section below that will allow us to determine if the specific application is suitable for the ceramic
resonator/filters that you have requested.
Ceramic Resonators/Filters, both surface mount and through-hole type, are a much different frequency control solution than that of a crystal
based device. Not only are there “matching” issues to specific integrated circuits and processors with ceramic based piezoelectric
components but for multiple reasons ceramics are not the most advantageous nor robust frequency control solution for certain applications.
In addition, ECS does not approve the use of its ceramic products in Automotive, Military, Avionics, Life Sustaining or Life Support
systems or any other related medical application.
If the customer chooses to use this product in one or more of the noted applications without the written consent of ECS, Inc., ECS,
Inc. shall be held harmless, and given release of liability and indemnification from claims of any nature.
Please complete the following and submit this form as soon as possible.
