NTC Accurate Thermistors
NP30 - NJ 28 – NI 24 – NK 20
High precision resistance and an outstanding ability to
reproduce the sensibility index B, make these ranges of
products the types of thermistors ideal for temperature
measurement applications.
Leaded or unleaded, these small size and rapid response
time thermistors are able to meet the most accurate
requirements.

PACKAGING AND KINK SUFFIXES
Tables below indicate the suffixes to specify when ordering to
get the required kink and packaging. For devices on tape, it
is necessary to specify the height (H or Ho) which is the
distance between the tape axis (sprocket holes axis) and
the seating plane on the printed circuit board. The following
types can be ordered on tape either in AMMOPACK
(fan folder) or on REEL in accordance with IEC 286-2.
– Straight leads:
H
represents the distance between the sprocket holes axis
and the bottom plane of component body (base of resin or
base of stand off).
– Kinked leads and flat leads:
Ho
represents the distance between the sprocket holes
axis and the base on the knee (kinked leads) or the bottom
of the flat part (flat leads).

TAPING CHARACTERISTICS
Missing components
A maximum of 3 consecutive components may be missing
from the bandolier, surrounded by at least 6 filled positions.
The number of missing components may not exceed 0.5%
of the total per packing module.
The beginning and the end of tape exhibit 8 or 9 blank
positions.
