• Manufacturer Part Number: 453312-100M-100KJF
• Description: High Voltage Planar Dividers
• Manufacturer: Welwyn Components

High Voltage
Planar Dividers
4530 Series
Construction
A high quality alumina substrate is printed with a specially
selected high voltage resistor ink based on a ruthenium
oxide/glass system. A choice of protective systems is available.
Choice of Protection
As standard components are supplied conformally coated
with an epoxy resin. By special request components can be
supplied unprotected or with a screen printed epoxy
‘handling’ protection.
Terminations
Material
Solderability Meets the requirements of IEC 115-1, Clause
Application Notes
The terminations should not be bent closer than 1.5mm from
the body, and the recommended minimum bend radius is 1mm.
Due to the high voltage which can appear between the resistor
body and any adjacent metal part, resistors should be mounted
at an adequate distance from other conducting parts.
Temperature Category
Lower temperature category is -55°C, upper temperature
category is 125°C. Due to the possibility of surface
condensation it is recommended that high voltage is not
applied to resistors in conditions of high humidity.
Design Flexibility
The experience of Welwyn engineers has been used to design
this generation of high voltage planar resistors to be suitable
for a majority of applications. However, should an application
require particular consideration, Welwyn designers are
available to provide advice and where applicable, to
recommend a non-standard product. Special sizes, designs
etc, can be prototyped at short notice.
Non Standard Optional Features
The options listed below are some of the special features
which may be provided, subject to agreement.
Special substrate size.
Leadless version with palladium silver solder pads.
Special termination length, diameter and pitch.
Special designs for pulse applications.
Resistance value outside stated range.
Multiple dividers R1, R2, R3 etc.
