Notes on mounting
When mounting these capacitors, take into account creepage distances and clearances to adjacent
live parts. The insulating strength of the cut surfaces to other live parts of the circuit is 1,5 times the
capacitors rated dc voltage, but is always at least 300 Vdc.
Capacitors with 7,5 mm lead spacing are only suitable for use with single-clad printed circuit boards.

1) Replace the + by the code letter for the required capacitance tolerance.
Replace the *** by the code number for the required packing form:
– For crimped leads (0,15 to 1,5 nF): Ammo pack = 249, reel = 149, untaped = 010
– For straight leads (2,2 to 6,8 nF): Ammo pack = 289, reel = 189
– The ordering code for untaped components ends after the tolerance code letter.
2) Capacitance tolerance: ±10 % =ˆ K
Capacitors with
C
R≤ 1,5 nF are only available with crimped leads.
Crimping increases the mounting height by approx. 4 mm
(also refer to “Taping and Packing”, page 279).
