- 20 VA at 400 Hz from a 115 VAC primary
- Series secondary: 20V C.T. @ 1A
- Parallel secondary: 10V @ 2A
- Epoxy cast to withstand shock and severe environments
- Two coil design: balanced windings, low magnetic radiation, no electrostatic shield
- PCB mount, 0.8 in max height, 0.04 in (1 mm) pin diameter
- 35 C temperature rise, 7.2% regulation
The 226N is a 20 VA, 400 Hz power transformer from the 226 Series, designed to mount on a printed circuit board and run from a 115 VAC primary. Its secondary is rated 20V C.T. @ 1A with the windings in series, or 10V @ 2A with them in parallel, giving designers two output options from one part.
The 226N is a 400 Hz model: at 20 VA from the smallest 226 case it delivers 1 A on its 20 V centre-tapped winding or 2 A at 10 V in parallel, with 7.2% regulation.
The transformer is epoxy cast to withstand shock and severe environments. A two coil design provides balanced windings and low magnetic radiation, so no electrostatic shield is required.
Per the series table, the 226N stands 0.8 in high (max) with a pin diameter of 0.04 in (1 mm); shipping weight is 0.3 lbs (0.14 kg). Temperature rise is 35 C and regulation is 7.2%. The part is RoHS and REACH compliant, and it is classified under UNSPSC 39121301.
Note: the manufacturer states that the 226-227-228 product line will soon be discontinued as a stocked series and is available while quantities last.
Ideal For
- On-board 20V centre-tapped or 10V supply for 115 VAC equipment
- 400 Hz PCB-mounted power conversion
- Circuit boards exposed to shock or severe environments
- Replacement of an existing epoxy-cast PCB transformer
