µ ,u or U=micro henry ; m=milli henry
PRODUCT SAFETY NOTICE
THE COMPONENTS DESIGNATED BY A SYMBOL ( ) IN THIS
SCHEMATIC DIAGRAM DESIGNATES COMPONENTS WHOSE
VALUE ARE OF SPECIAL SIGNIFICANCE TO PRODUCT SAFETY.
SHOULD ANY COMPONENT DESIGNATED BY A SYMBOL NEED TO
BE REPLACED, USE ONLY THE PART DESIGNATED IN THE PARTS
LIST.
DO NOT DEVIATE FROM THE RESISTANCE, WATTAGE AND VOLTAGE RATINGS SHOWN.
EXPLANATORY NOTES (EXAMPLES)
