ALP/t 20/22 Series 85°C
• Solder tag (ALT) and DIN standard solder pin (ALP)
• Long Life 26000 hours at 85 °C (Ur, Ir applied)
• ALC snap-in should be considered for new designs
APPLICATION BASIC DESIGN

Test Condition:
UR, 5mins., 20°C
It should be pointed out that the ALP,
solder pin, ranges are an older design and
as such should not be considered for any
new applications. Details are incorporated
here, primarily, for maintenance/replacement
purposes.
The ALP/T20 features low ESR, high ripple
current ratings and outstandingly good high
frequency impedence.
The ALP/T22 has the same features as the
ALP/T20 series but with a very high CV per
unit volume.
