SL1021A/B Series

RoHS

SL1021A/B Series

Description

GDT circuit protection devices dissipate electrical

surge energy safely within a contained plasma gas.

Commonly used to help protect sensitive telecom

and networking equipment and lines, GDTs protect

from damage that may result from lightning strikes

and equipment switching operations.

The Littelfuse GDT series described in this document

are available in a variety of leaded and surface mount

forms and offered with and without optional fail-safe

clip. Please refer to the electrical speciﬁcations,

dimension and packaging options section of this

document for additional information.

SL1021A/B Series:

Agency Approvals

SL1021A/B series GDTs are designed to offer high

levels of performance on fast rising transients in the

range of 100V/μS to 1KV/μS, which are those most

likely created by induced lightning disturbances.

AGENCY

AGENCY FILE NUMBER

E128662

These devices feature ultra low capacitance (typically

1.5pF or less) and are extremely robust with SL1021A

devices able to divert a 10,000 Amp pulse without

destruction, and SL1021B sufﬁx devices able to divert

a 20,000 Amp pulse without destruction.

3 Electrode GDT Graphical Symbol

a =TIP

b = RING

These series offer optimized internal geometry which

provide low insertion loss at high frequencies, ideal

for the protection of broadband and other high speed

transmission equipment.
