Product News for Selenium Filter
SELENIUM SURGE SUPPRESSORS Used as semiconductor in rectifiers and suppressors for many years, selenium occurs naturally on the earth. Its popularity as a rectifier is fading in favor of its silicon equivalent. However, demand for selenium suppressors continues. Depositing the elements on a metal substrate's surface produces selenium cells. This provides the cells with good thermal mass and energy dissipation as well as "self-healing" characteristics, allowing the device to survive energy discharges in excess...

American Microsemiconductor, Inc.
Selenium Diodes from American Microsemiconductor Let American Microsemiconductor replace your selenium rectifier with a more reliable, less expensive, eco friendly, direct replacement silicon rectifier. Selenium rectifiers are seldom specified, designed, or used today. They were among the earliest of semiconductor rectifiers. Even earlier than germanium diodes! Selenium comes from the Greek word for blue, selene. They give off a garlic like smell when they are overstressed and they are toxic. Selenium rectifiers have been in use for over 60...

Bandpass Filters Band-pass filters are usually divided in two groups: 1. Broadband pass filters, and 2. Narrowband pass filters. Although there are no bandwidth values that define narrow or broad filters in UV or visible or in IR, it is common to consider filters that have bandwidth 2% or less of the central or peak wavelength as narrowband. Thus, according to this convention, the band-pass filter centered at 500 nm is considered as narrowband if the pass band has bandwidth of 10 nm or less. Band-pass filters... (read more)
