ORDERING INFORMATION

1. For RoHS version - C-4 *

2. For Pulse type - C-4 I

3. For Non Inductive type - N C-4

4. For Tape / Reel - C-4 TR

5. C4* GS - “GS” stands for grey silicon - applicable for customer who washes PCB with solvents.

HEA series enjoys a wide market in audio and TV field.

Apart from these applications and as they are available in close tolerance, they have increasingly found favour with OEM’s in the industrial

field, especially where the following properties are required -

High degree of insulation

b) Low surface temperature

Depending on resistance value and application, the resistors core may be fiberglass or ceramic. These resistors are also available for use

in pulse application. For further information please refer to “Pulse / Surge capability of resistors”.

In case tailor-made pulse resistor is required, please refer to “Questionnaire of data required” and provide data accordingly.

Note:

Due to recent technological advances, the ceramic cases used may be steatite ceramic or corderite ceramic or high alumina ceramic

depending on the nature of the application. Hence the ceramic cases may be off-white or variations of brown and variations of grey;

colours which are inherent to these ceramic materials.

In case the device is to be subjected to aggressive solvents, please inform factory so case filling can be changed to solvent resistant

type.

TAPING : Types C-2A, C-4 , C-5B , C-6 , C-7A , C-9 , C-10A , C11 can be supplied in taped form. Please refer to Tape / Reel specifications.
