(See table below)
L= L dimension (mm) max. W= Wattage/Package (mW) max.
• Various types of standard circuits in different sizes and
power are available. (Seated height 0.20" (5.08mm),
0.26" (6.5mm), 0.42" (10.7mm) Max.)
• Higher temperature soldering of the leads prevents
terminals from loosening during board assembly
• For automatic insertion machines, stick magazines
(the tip of lead terminal is cut to a V shape) and taping
packages (TBA: All leads taping, TPA, TUA: 3 leads taping)
are applicable.
• Products with lead-free terminations meet EU RoHS
requirements. EU RoHS regulation is not intended for
Pb-glass contained in electrode, resistor element and glass.
*1 The symbol “S” showing 1.8 pitch is added to the type designation after the circuit symbol.
