■Features
6.5mm(DF57H-4pos)
1. 4A current rating
The space-saving design utilizes two power
contacts that can carry up to 4A of current, and
signal contacts that can also carry 0.3A of
current. This is all delivered in a small connector
that features a small mounting depth of 2.64mm.

0.72mm
2. Two point contact structure
The structure utilizes two points on each contact to
ensure a secure connection for both types of
contacts (power and signal). (Fig.2.3)
3. Good mating operability
The connector contributes to the enhanced mating
operability by giving a click feeling which is effective in
preventing incomplete mating, and mating selfalignment of 0.3mm which is secured by the guide ribs.

[Condition]
1. Peak temperature
2. Heat section
3. Preheat section
4. Number of reflow cycles
: Maximum of 250ç
: 220ç min., within 60 seconds
: 150 to 180ç, 90 to 120 seconds
: Maximum of 2 cycles
Note 1: The temperature represents the PCB surface temperature in the vicinity of the
connector lead section.
Note 2: For the use of Nitrogen reflow, mount the connectors with an oxygen density
of 1,000 ppm or higher. Consult Hirose for the condition less than 1,000 ppm.
2. Recommended manual
soldering condition
Soldering iron temperature: 340 ±10°C, soldering time: within 3 seconds
3. Recommended stencil
thickness and open area ratio
to PCB pattern area
Thickness: 0.1 mm
Open area ratio: 85% for signal contact, and 60% for power contact on the Receptacle
side. 70% for both contacts on the Plug side
4. Board warpage
Maximum of 0.02 mm in the center of the connector, while using both ends of the
connector as reference point
5. Cleaning conditions
We do not recommend cleaning these connectors. Cleaning them may alter the
mating/un-mating operations. If you do clean them, make sure you test that these
operations have not been compromised prior to use.
6. Precautions
●Do not mate or un-mate these connectors until they are mounted, failure to follow
this precaution can lead to deformation or damage to these connectors.
●Provide another form of support to the PCB, this connector was not designed to be
the main form of support.
●When mating/un-mating this connector, do not apply excessive twisting forces onto
the connector. These forces can damage the contacts and alter its performance.
●Do not apply excessive amounts of flux as it may cause the flux to wick.
●There may be a slight variance in the color of the molding between production lots;
this variance will not affect the performance of the connector.
●Refer to the next page for the handling precautions when mating and un-mating
these connectors.
●If the connector becomes disconnected due to impact, a fall or a counterforce to
the FPC, it may be necessary to hold the connector in place with an addition to the
device’s case or other cushioning material to hold the connector in place.

Handling Precautions when Mating Connectors
BM22-S-V

BM22L-P-V
Prior to mating, locate the guidance ribs and align the
header. Do not apply excessive force during the mating
process as it may damage the contacts.
Incorrect
Incorrect
When the connector has been correctly aligned, the
header will be parallel to the receptacle. An even force
can now be applied to the header to mate it with the
receptacle until it is fully mated.

Handling Precautions when Un-mating Connectors
BM22-S-V
Dec.1.2021 Copyright 2021 HIROSE ELECTRIC CO., LTD. All Rights Reserved.
BM22L-P-V
To un-mate this connector, lift evenly across the
header. Make sure that each side of the connector
stays parallel to the other.
Correct
Correct
If circumstances prevent the connectors from staying
parallel to each other, then one side may be lifted as
shown in the diagram. This method is only approved if
the connector is mounted onto an extremely rigid circuit
board. If the board were to warp during this process
it may result in damage to the connector or its solder
joints.
Pitch orientation
Correct
Corner orientation
Incorrect
Do not try to disconnect these connectors by pulling
on one side or a single corner, or to un-mate it when
it is hasn’t been securely mounted onto a rigid FPC.
These actions may lead to deformities and ultimately
a damaged connector. Prior to the mounting of these
connectors we recommend that you check the rigidity of
your FPC to ensure that it meets the standards needed
to support these connectors.
If the FPC is not strong enough by itself, a stiffener may
be applied. If the FPC has a low rigidity the connector
may break (as shown in the illustration to the left).
We recommend a backing of no less than 0.3 mm of
glass epoxy and 0.2 mm of stainless material.
