Reliability Testing Verifies Performance of Gowanda's SMRF1812 Inductors

Gowanda, NY (USA) – Gowanda Electronics announces the introduction of a new series of surface mount inductors – SMRF1812 – that offers a robust design with reliable performance, as verified by severe reliability testing. This new series is targeted for use in RF applications where board manufacturers require rugged inductors that will withstand the demands of harsh soldering processes.

Gowanda Electronics’ proprietary manufacturing process for the SMRF1812 series maximizes the robustivity of the device. This is accomplished by centering the coil within the device to maximize stress on internal component parts, and by incorporating a high temperature magnet wire. The design also utilizes a semiconductor grade epoxy molding compound to enhance product quality and reliability.

Reliability testing of the SMRF1812 inductor series was completed by Gowanda Electronics and validates the performance.

Testing began with preconditioning of the SMRF1812 inductors via 4 cycles of reflow soldering that peaked out at 250°C for 30 seconds, followed by 1 cycle of complete solder submersion at 245°C. The preconditioned components then passed the following tests: 200 cycles of thermal shock, 2000 hours of life test (full load), 1000 hours of 85/85 humidity with load, drop test (1 meter, 10 times), and shear test (4.4 pounds). This rugged testing demonstrates product reliability under the most adverse conditions.

Applications of the SMRF1812 inductors include all RF signal circuitry in communications equipment, test & measurement equipment, medical diagnostic equipment and industrial process control equipment. Other applications include use in computers, disk drives, modems and other computer peripherals, as well as in security systems, instrumentation, bar code and laboratory analysis equipment, aviation equipment, navigation equipment, electronic test equipment and cable TV.
