Low Resistance Resistors (NE)Thumbnail Gallery
Token advanced film (NE) low resistance ultra precision resistors spell high precision. A homogenous film of metal alloy is deposited on a high grade ceramic body. After a helical groove has been cut in the resistive layer, tinned connecting wires of electrolytic copper are welded to the end-caps.
The resistors are moulding which provides electrical, mechanical, and climatic protection.
Token has complete capability to develop specific reliability programs designed to customer requirements. Products equate Vishay, Ohmite, Caddock, IRC, EBG, Panasonic Precision Devices with more competitive price and fast delivery.
Full line products meet RoHS compliant. Detailed specifications, both mechanical and electrical, can be download here Precision Low Ohmic Resistors PDF (318KB), or contact our sales representative for more information.
The NE series meets the electrical, environmental and dimensional requirements of MIL-PRF-55182.
Referencing to Chinese National Quality Standard GJB244A-2001.
