HTU21D(F) Sensor
Digital Relative Humidity sensor with Temperature output
Packaging Type
HTU21D(F) sensors are provided in DFN packaging. DFN stands for Dual Flat No leads.
The HTU21D(F) sensor chip is mounted to a lead frame made of Cu and plated with Ni/Pd/Au. Chip and lead
frame are over molded by green epoxy-based mold compound. Please note that side walls of sensors are diced
and hence lead frame at diced edge is not covered with respective protective coating.
The total weight of the sensor is 0.025g.
Traceability Information
All HTU21D(F) sensors are laser marked with an alphanumeric, five-digit code on the sensor as pictured below.
The marking on the HTU21D(F) sensor consists of two lines with five digits each:
The first line denotes the sensor type: HTU21.
The second line denotes several information as:
o The first digit of the second line defines the output mode:
D = digital and I²C
P = PWM
S = SDM
o The second digit defines the manufacturing year: 2 = 2012, 3 = 2013, etc.
o The last three digits represent an alphanumeric tracking code. That code can be decoded by
MEAS only and allows for tracking on batch level through production, calibration and testing and
will be provided upon justified request.

Reels are also labeled, as displayed below and give additional traceability information.
