Surface Mount
Planar Transformers
| New RoHS part numbers are shown. Lead was removed from internal parts. The next to the last character is an L to indicate RoHS compliance. (View old data sheet.) |
- Low profile surface mount planar design, less than 10 mm high
- Planar technology offers excellent reliability and repeatability
- Designed for push-pull topologies at 200 – 300 kHz
- Auxiliary winding can control input to PWMs
- 1500 Vrms primary/secondary isolation
- Custom designs available
- RoHS-compliant. 260°C compatible. Matte tin over nickel over brass terminations.

| 1 | When ordering, please specify packaging code: e.g. A0027-ALD | |
| Packaging: |
D = 13" reel, machine-ready EIA-481 embossed plastic tape (250 parts per full reel). B = Less than full reel In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead. |
|
| 2 | Inductance measured across primary at 250 kHz, 0.1 Vrms, 0 Adc. | |
| 3 | Ambient temperature range: | –40°C to +85°C |
| 4 | Storage temperature range: | Component: –40°C to +85°C T&R packaging: –40°C to +80°C |
| 5 | Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between. | |
| 6 | Electrical specifications at 25°C. | |
| Refer to Soldering Coilcraft Components before soldering. | ||
