Gull Wing Leads

Option

0.000

Weight: 15 grams max.

Dimensions in inches (mm)

Tolerance±0.005 (0.13) for three decimal places,

±0.01 (0.3) for two decimal places, unless otherwise specified

Please refer to the numerical dimensions for accuracy.

CAUTION

Maximum reflow temperature is 220°C for a maximum of 30 seconds.

SN60, SN62, or SN63 are the recommended types of solder. See MGA

gull-wing solder pads layout. Hand soldering should not exceed 300°C

for 10 seconds per pin.

The triangle (ESD) marking on the cover indicates pin one.

Cover marking is oriented with pin one at the upper right corner.

The straight lead configuration does not require a “case designator”

in the model number. ex. MGA2805S

The gull wing option

(configuration) requires

“Z” as a “case

CASE D1 GULL-WING PADS

Case D1 MGA Solder Pads, Rev F, 2013.05.31

Dimensions in inches (mm)

Tolerance±0.005 (0.13) for three decimal places ±0.01 (0.3) for

two decimal places, unless otherwise specified.

Please refer to the numerical dimensions for accuracy.

CAUTION:

Internal components are soldered with SN96 (melting

temperature 221°C) to prevent damage during reflow. Maximum

reflow temperature for surface mounting the MGA converter is

220°C for a maximum of 30 seconds. SN60, 62, or 63 are the

recommended types of solder.

Hand soldering should not exceed 300°C for 10 seconds per pin.

SOLDER MASK NOTES

1. Pad dimensions are for the solder mask. Leads common to

each other can be connected to each other as desired.

2. Ground (case) pins should be connected to the center pad for

improved grounding.

3. Connect "no connection" pins to case ground to reduce EMI.

4. Center pad should not have a solder mask. Solder, copper, or

Au/Ni plate are preferred over solder mask for adhesive attach.

5. Pre-tin base of converter prior to soldering.

6. If less rotation of case is desired, reduce the width of the large

case pad by 0.020 inches (0.51 mm). Pad length can be

extended 0.010 inches (0.25 mm) towards the case body and an

as-desired dimension away from the case body.

7. Do not exceed 220°C as measured on the body of the

converter (top or bottom).

8. Attach the body of the case to the board with a thermally

conductive adhesive or SN60, 62, or 63 solder. The adhesive

can be electrically conductive as well. It can be applied as an

underfill post solder or dispensed and cured prior or during

solder.

9. In the presence of vibration, to ensure reliable mechanical

attachment, the body of the case should be attached with

adhesive or solder as noted above (note 8). The leads alone do

not provide sufficient mechanical attachment.
