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.
Futaba 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.

(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.
