Cylindrical thin-film inductors

16 Feb 2000 Passive Components

BC Components has launched its first range of inductors. The cylindrical thin-film inductors have a high self-resonant frequency (SRF), capable of working up to 2 GHz, claims the manufacturer. They also have high current capability, making them ideal general-purpose inductors for most high frequency (HF) applications. They are particularly suitable for use in high volume HF applications, such as TV tuners, cable and satellite TV systems, cellular telephone infrastructure and remote control devices.

Cylindrical thin-film inductors are particularly well suited for use in the pick-and-place machines required for high volume manufacture. They have standard dimensions and, unlike flat chip inductors whose characteristics depend on the placement positioning, their behaviour is independent of orientation, says the company. Cylindrical thin-film inductors are also tolerant of far greater current surges.

The new components are available both in MINI-MELF (type number IMA 0204) and MICRO-MELF (type number IMU 0102) formats. Inductance values are from 10-100 nH, with tolerances of ±10% and self-resonant frequencies (SRF) from 1500 MHz to greater than 4000 MHz.
