Low TCR High Precision Resistors (EE)
(EE) Low TCR Resistors - Introduction
Low TCR high precision resistors offer more precision design options
<
>
Known for providing design engineers with a comprehensive range of military-qualified resistive precision devices, Token Electronics Advanced Metal Film has further expanded its military product capabilities.
These cost-effective high precision moulding resistors meets ROHS requirements, MIL-PRF-55182, and GJB244A-2001 quality standards.
EE Series manufactured by depositing a homogeneous film of metal alloy onto a high-grade ceramic body, the metal film resistors are moulded into cylinder shape to provide mechanical, electrical and climatic protection.
EESeries equate Vishay, IRC, EBG, Panasonic Precision Devices with more competitive price and fast delivery. Contact us with your specific needs. PDF download here High Precision Low TCR Resistors (EE)
