scope:

This drawing forms a part of a one part - one part number documentation system (see 6.6 herein). This drawing describes device requirements for hybrid microcircuits to be processed in accordance with MIL-H-38534. Two product assurance classes, military high reliability (device class H) and space application (device class K) and a choice of case outlines and lead finishes are available and are reflected in the Part or Identifying Number (PIN). When available, a choice of radiation hardness assurance levels are reflected in the PIN.

The PIN shall be as shown in the following example:

Device classes H and K RHA marked devices shall meet the MIL-H-38534 specified RHA levels and shall be marked with the appropriate RHA designator. A dash (-) indicates a non-RHA device.

The device type(s) shall identify the circuit function as follows:

Device type Generic number Circuit function 01 ATR2815TF/CH DC/DC converter, 30 W, +5 V, ± 15 V triple output

This device class designator shall be a single letter identifying the product assurance level as follows:

Device class Device requirements documentation H or K Certification and qualification to MIL-H-38534

The case outline(s) shall be as designated in MIL-STD-1835 and as follows:

Outline letter Descriptive designator Terminals Package style Z See figure 1 10 Flange mount

The lead finish shall be as specified in MIL-H-38534 for classes H and K. Finish letter "X" shall not be marked on the microcircuit or its packaging. The "X" designation is for use in specifications when lead finishes A, B, and C are considered acceptable and interchangeable without preference.

Input voltage range ........................... −0.5 V dc to +50 V dc Power dissipation ............................ 14 W Lead temperature (soldering, 10 seconds) ..... +300°C Storage temperature ........................... −65°C to +150°C

Input voltage range ............................ +16 V dc to +40 V dc Output currents: +5 V output 2/ 3/ ........................... +100 mA to +4000 mA ±15 V output 2/ 3/ ........................... +500 mA Output power 2/ 4/ ............................ ≤ 30 W/ Case operating temperature range (T_C) .......... −55°C to +125°C

intended Use:

Microcircuits conforming to this drawing are intended for use for Government microcircuit applications (original equipment), design applications, and logistics purposes.
