Marking Information
All encapsulated capacitors are marked with: Capacitance value, tolerance,
rated d.c. voltage, dielectric, and where size permits the Syfer Technology
‘S’ logo.
Example: 1000pF ± 10% 50V 2X1 Dielectric
Syfer Technology produces a wide range of dipped radial leaded capacitors. These are
available in rated voltages of 50V up to 12kV. Our larger case sizes and high voltage
versions are particularly in demand, especially for mil/aero and medical power supply
applications. Please contact our Sales Office to discuss any special requirements.

Wave Soldering
Wave soldering is generally acceptable, but the thermal
stresses caused by the wave have been shown to lead to
potential problems with larger or thicker chips.
Maximum permissible wave temperature is 260˚C for Radial
Leaded capacitors.
The total immersion time in solder should be kept to a
minimum. It is strongly recommended that Sn/Ni plated
terminations are specified for wave soldering applications.
REACH (Registration, Evaluation, Authorisation and
restriction of Chemicals) Statement
The main purpose of REACH is to improve the protection of
human health and the environment from the risks arising from
the use of chemicals.
Syfer Technology Ltd maintains both ISO 14001,
Environmental Management System and OHSAS 18001 Health
& Safety Management System approvals that require and
ensure compliance with corresponding legislation such as
REACH.
For further information, please contact the sales office at
SyferSales@knowles.com
Hand Soldering Radial Leaded Capacitors
Radial capacitors can be hand soldered into boards using
soldering irons, provided care is taken not to touch the body of
the capacitor with the iron tip. Soldering should be carried out
from the opposite side of the board to the radial to minimise
the risk of damage to the capacitor body. Where possible, a
heat sink should be used between the solder joint and the
body, especially if longer dwell times are required.
RoHS Compliance
Syfer routinely monitors world wide material restrictions (e.g.,
EU/China and Korea RoHS mandates) and is actively involved
in shaping future legislation.
All standard Radial Leaded capacitors are compliant with the
EU RoHS directive. Compliance with EU RoHS directive
automatically signifies compliance with some other legislation
(e.g., Korea RoHS). Please refer to the Sales Office for details
of compliance with other materials legislation.
Most radial components are available with non-RoHS compliant
tin/lead (SnPb) solderable lead finish for exempt applications
and where pure tin is not acceptable.
Check the website, www.knowlescapacitors.com/syfer for
latest RoHS update.
