Split Bobbin
PCB TYPE, SPLIT BOBBIN, HIGHLY ISOLATED TRANSFORMERS
FEATURES OF "DB" & "DDB" TRANSFORMERS ARE:
1- High isolation-pass 2500V RMS hipot.
2- No crossovers of primary & secondary leads.
3- Low coupling capacitance-no electrostatic shield necessary.
4- PC pins allow direct insertion in PC boards.
Note: Special Rating and Variations Are Also Available And Will Be Quoted And Shipped Promptly.

* Apparent Power P is in Volt Ampere [VA], Vp is the output voltage in Volt [V]
Part Number Example:
Transformer Part Number: DDB-4-12-P
Transformer specification:
Primary Input Dual Winding; Apparent Power P = 6 VA; Parallel Output Winding 2x @ 6.3 Volt,
Current I = 6.o [VA] / 6.3 [V] = 0.95 [A] (approximately 1 Ampere)
