This New Product Brief (NPB) is part of a video series highlighting the features, applications, and technical specs of newly-released products.

PANASONIC ERJ-UxR Anti-Sulfur Thick Film Chip Resistors

Panasonic ERJ-U2R, ERJ-U3R, and ERJ-U6R thick film chip resistors offer high precision and high resistance to sulfurization for reliable operation in automotive designs, home appliances, and many other applications. 

The resistors use a silver-palladium-based inner electrode to achieve high anti-sulfurization characteristics and prevent open circuit failures, with three layers of electrodes and a metal glaze thick film resistive element to ensure high reliability. The resistors have a ±0.5% resistance tolerance, with values ranging from 100Ω to 100kΩ. 

They also have a low TCR for stable resistance across the -55°C to +155°C temperature range, and the devices are AEC-Q200 Grade 0 compliant. Panasonic ERJ U2R, U3R, and U6R resistors are available in 0402, 0603, and 0805 case sizes, with power ratings up to 1/8th of a watt.
