DLFP

-	Linear/saturating	choke -	Wire	leads -	Low	noise	development	by	using	iron	powder	toroids	instead	of	conventional	iron	lamination	cores -	Fully	potted	resign

Description

Applications

-	Phase	angle	control	circuits	with	thyristors,	triacs	or	transistors -	The	choke	acts	at	its	optimum	when	it	is	mounted	directly	at	the	interference	originator	(thyristor,	triac)
