SMT Planar Transformer

–

A9845-AL

Coilcraft’s surface mount planar transformers are ideal for

applications that require high efficiency in a low-profile

package.Theyaredesignedtoperforminpush-pulltopolo-

gies operating at 200 – 300 kHz. The auxiliary winding can

be used to control input current to PWMs.

Planar transformers offer high power densities along with

greatreliabilityandrepeatability.

The A9845-A has a smaller footprint and lower profile than

ourotherplanartransformers.Thecircularwindingsprovide

very low DCR and excellent leakage inductance values.

To complete your design, Coilcraft offers a wide variety

of power inductors for use as input and output chokes. To

1. When ordering, please specify packaging code:

A8945-ALD

1. Inductance measured between pins 2 and 4 at 250 kHz, 0.1 Vrms,

0 Adc.

2. Storage and ambient operating temperature range: –40°C to +85°C.

3. Electrical specifications at 25°C.

Packaging: D = 13″ machine ready reel. 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.
