RTL (Retention Time Limited)
Notes:
1. The marking (RTL) indicates that the Retention Time is
limited for this item.
After the discontinuation of this assembly in production, the
item will continue to be available for a specific period of
time. The retention period of availability is dependent on the
type of assembly, and in accordance with the laws
governing parts and product retention.
After the end of this period, the assembly will no longer be
available.
2. Important safety notice
Components identified by mark have special
characteristics important for safety. When replacing any of
these components, use only manufacture´s specified parts.
3. The S mark indicates service standard parts and may differ
from production parts.
4. ISO code (Example : ABS-HB) of the remarks column
shows quality of the matterial and a flame resisting grade
about plastics.
5. RESISTORS & CAPACITORS
Unless otherwise specified;
All resistors are in ohms (Ω) K=1000Ω, M=1000kΩ
All capacitors are in MICRO FARADS (µF) P=µµF
