Philips Components

Product speciﬁcation

Standard metal ﬁlm resistors

SFR16S/25/25H

type SFR16S; light-green for type

SFR25 and red-brown for type

SFR25H) which provides electrical,

mechanical and climatic protection.

The encapsulation is resistant to all

cleaning solvents, in accordance with

“MIL-STD-202E, method 215”, and

“IEC 60068-2045”.

FEATURES

DESCRIPTION

• Low cost

A homogeneous film of metal alloy is

deposited on a high grade ceramic

body. After a helical groove has been

cut in the resistive layer, tinned

connecting leads of electrolytic

copper are welded to the end-caps.

• Low noise

• Small size (SFR16S).

APPLICATIONS

The resistors are coated with a

coloured lacquer (light-blue for

• General purpose resistors.
