Miniature Axial-Leaded Thick Film Resistor Suits Hearing Aids

Vishay Intertechnology, Inc. introduced a miniature axial-leaded thick film resistor designed for hearing aids and high-frequency probe tips for testing in industrial applications. Encapsulated in a robust plastic housing, the Vishay Techno HML combines an ultra-compact 1.85 mm by 0.91 mm case size with high-temperature performance and a non-inductive design.

The HML series resistor released today offers a power rating of 0.063 W at +70 °C and a maximum working voltage of 50 V over a temperature range of -55 °C to +150 °C. The HML features a resistance range of 1Ω to 22 MΩ, with tolerances down to ± 1 % and temperature coefficients to ±100 ppm/°C. Offering 100 % pure tin solder coating on nickel lead wires, the RoHS-compliant device is suitable for soldering and welding.

Samples and production quantities of the HML are available now, with lead times of eight weeks. Pricing for U.S. delivery varies by resistance, tolerance, and temperature coefficient. For example, pricing for resistors with tolerance of ±5% starts at $2.90 per piece in 1,000-piece quantities.
