Specification
of Semi-finished Products |
|
| The semi-finished products indicate
either film-coated rods or sorted cap rods. These semi-finished
objects can be processed further by steps of film-cutting,
lead wire welding and resin coating to produce the resistors.
We can provide both film-coated rods and sorted cap rods.
Based on the aluminum oxide content in the sintering formulation
of the rods, the rods can be categorized into 75% and 85%.
Thought this content is not fixed and we can always customize
to fulfill customer's needs. There are two kinds of resistive
film available: Ni-P alloy film and Tin oxide film. The
size of the rods available is flexible and can be customer
made.

| ◆Illustration of alphanumeric
code : |
| (1). Coating (2 digits): MO=Tin oxide film; MN=Ni-P
alloy film. |
| (2). Rod type (3 digits): Based on the codes provided
by the rods supplier. |
| (3). Dimension (4 digits): first two digits indicate
diameter and the last two digits indicate length. |
| (4). Capping (1 digit): " + " = sorted cap
rods; " - " = film-coated rods |
| (5). Resistance range (6 digits): The first and the
last three digits show the resistance range. |

The detailed tables for film-coated
rods and sorted cap rods are listed Table-7 and
Table-8. |
