Pressure sensors
Pressure transmitters without stainless steel housing (voltage output) CAU-T series
Handling/ Mounting (dies)
Pressure sensor dies should be handled appropriately and not be touched with bare hands. They
should only be picked up manually by the sides using tweezers. Their top surface should never be
touched with tweezers. Latex gloves should not be used for handling them, as this will inhibit the
curing of the adhesive used to bond the die to the carrier. When handling, be careful to avoid cuts
caused by the sharp-edged terminals. The sensor die must not be contaminated during manufacturing
processes (gluing, soldering, silk-screen process).
The package of pressure sensor dies should not to be opened until the die is mounted and should be
closed after use. The sensor die must not be cleaned. The sensor die must not be damaged during
the assembly process (especially scratches on the diaphragm).
Soldering (transducers, transmitters)
The thermal capacity of pressure sensors is normally low, so steps should be taken to minimize the
effects of external heat. High temperatures may lead to damage or changes in characteristics.
A non-corrosive type of flux resin should normally be used and complete removal of the flux is
recommended. Avoid rapid cooling due to dipping in solvent. Note that the output signal may change
if pressure is applied to the terminals during soldering.

Display of ordering codes for TDK Electronics products
The ordering code for one and the same product can be represented differently in data sheets, data books,
other publications, on the company website, or in order-related documents such as shipping notes, order
confirmations and product labels. The varying representations of the ordering codes are due to different
processes employed and do not affect the specifications of the respective products. Detailed
information can be found on the Internet under www.tdk-electronics.tdk.com/orderingcodes.
