MICROWAVE LOW NOISE AMPLIFIER
NPN SILICON EPITAXIAL TRANSISTOR
SUPER MINI MOLD
DESCRIPTION
The 2SC4187 is designed primarily for use in low voltage and low
current application up to UHF band. The 2SC4187 is ideal for pagers,
electro-optic detector postamplifier applications, and other battery pow-
ered systems. Super mini mold package makes it suitable for use in small
type equipments such as HICs.
