BF511

DISCRETE SEMICONDUCTORS DATA SHEET BF510 to 513 N-channel silicon field-effect transistors Product specification File under Discrete Semiconductors, SC07 December 1997 Philips Semiconductors Product specification N-channel silicon field-effect transistors DESCRIPTION Asymmetrical N-channel planar epitaxial junction field-effect transistors in the miniature plastic envelope intended for applications up to the v.h.f. range in hybrid thick and thin-film circuits. Special features are the low feedback capacitance and the low noise figure. These features make the product very suitable for applications such as the r.f. stages in f.m. portables (BF510), car radios (BF511) and mains radios (BF512) or the mixer stage (BF513).
