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)
